facetFilter没有从API请求返回预期的过滤响应

Question

我试图过滤任天堂的Algolia回应，这样我就只能得到带有dlcType的非"个人"游戏，但出于某种原因，它不适合我。然而，如果我facetFilter一个包含数组的字段(例如可用性字段)，它工作得很好。

这是我的请求:

{
"requests": [{
"indexName":"store_game_en_us", 
"params":"query=overcooked&hitsPerPage=5&page=0&analytics=false&facetFilters=%22dlcType%3A-Individual%22"
}]
}

这是我得到的响应/未经过滤:

Answer 1

首先确保该属性是作为faceting的属性添加的，您可以使用API或Algolia仪表板来查看

根据文档facetFilters需要是一个数组。从我看到的，你把它设置成像facetFilters:"dlcType:-Bundle"这样的字符串。相反，你需要facetFilters:["dlcType:-Bundle"]
，因此params将变成"query=overcooked&hitsPerPage=5&page=0&analytics=false&facetFilters=%5B%22dlcType%253A-Bundle%22%5D"

即使使用encodeURI，手写params作为字符串也是很麻烦的。相反，您可以将params定义为Javascript对象。下面是一个演示游乐场的请求数组的示例结构。您可以在这里学习编写facetFilters数组的规则

{
"requests": [
{
"indexName": "bestbuy",
"params": {
"query": "app",
"hitsPerPage": 7,
"maxValuesPerFacet": 3,
"page": 0,
"facets": [
"category"
],
"tagFilters": "",
"facetFilters": [
[
"category:Cell Phone Cases & Clips",
"category:Cases, Armbands & Watchbands"
]
]
}
},
{
"indexName": "bestbuy",
"params": {
"query": "app",
"hitsPerPage": 1,
"maxValuesPerFacet": 3,
"page": 0,
"attributesToRetrieve": [],
"attributesToHighlight": [],
"attributesToSnippet": [],
"tagFilters": "",
"analytics": false,
"clickAnalytics": false,
"facets": "category"
}
}
]
}

使用它并查看网络请求以了解requests数组结构。
